Which throat do you haveIJ The early model Ns are very limited as to what you can use. The later Ns used the same throat as the R5_6_7 and will pick up and use an 800 series with little changes. The later throat has different hooks and connections and is longer than the early Ns. My 82 N6 S3 came with the later_longer throat and can use the 300-800 series heads. Hope this helps!
